1604.14.22 - In containers weighing with their contents not over 7 kg each, and not the product of any insular possession of the United States, for an aggregate quantity entered in any calendar year not to exceed 4.8 percent of apparent United States consumption of tuna in airtight containers during the immediately preceding year, as reported by the National Marine Fisheries Service

This HTS category specifically classifies certain preparations of tuna and skipjack within airtight containers, prepared in a manner that excludes the addition of oil. The key defining characteristic is their packaging and presentation: they must be presented in containers weighing, with their contents, not more than 7 kilograms each. Furthermore, these goods are not sourced from any insular possession of the United States and are subject to specific annual quantity limitations based on reported United States consumption.

This detailed specification distinguishes this subcategory from its sibling, 1604.14.30 "Other," which would encompass tuna and skipjack in airtight containers, not in oil, that do not meet the specific weight, origin, or annual quantity limitations outlined in this classification. The limitations are critical for determining the correct tariff treatment and ensuring compliance with trade regulations.

Within this classification, further distinctions are made based on the specific species of tuna or if the product is from a different tuna species. The subcategories allow for the precise classification of either "Albacore (Thunnus alalunga)" or "Other" tuna and skipjack preparations that fit the overarching criteria of being in airtight containers, not in oil, and meeting the specified packaging and quantity restrictions.
